Can be summarised to ‘fit fence properly’ (2,6)
I believe the answer is:
in effect
'properly' is the definition.
Both the answer and definition are adverbs. Maybe they are linked in a way I don't understand?
'can be summarised to fit fence' is the wordplay.
'fit fence' can be anagrammed to 'IN EFFECT'.
Though, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for in effect that I've seen before include "Working," , "In reality" , "In force or in practice" , "Really; operating" , "Really, as a matter of fact" .)
